Abstract
The utility model provides a kind of engine charge pre-flock system, in order to improve the turbidity test of engine charge, pre-chimney filter, eddy flow fan, steam outlet pipe, support is being comprised along the arrangement of engine charge direction, the high velocity air entered by engine charge promotes eddy flow fan and rotates generation swirling eddy, density is greater than the impurity such as moisture and dust of air density under the centrifugal action of High Rotation Speed air-flow, discharge along the interlayer between pre-flock inner tube wall and steam outlet pipe outer wall, and clean air is entered in engine aspirating system by steam outlet pipe.
Description
Technical field
The utility model relates to automotive engine air intake system technical field, is specifically related to a kind of engine charge pre-flock system.
Background technique
The effect of the gas handling system of automobile provides clean, dry, that temperature is suitable air to carry out burning to reduce engine scuffing to greatest extent and keeping best engine performance to motor.Therefore require that gas handling system has very high filtering efficiency, the dust in removing air and moisture.
Commercial car operating conditions is severe, traditional Design of Inlet is for preventing automobile in the course of the work, dust in air and moisture enter into gas handling system, engine inlets suction port becomes 90 degree or inverse relationship towards with the direction of travel of automobile, in order to dedusting, the object that dewaters in inlet structure originally, the pressure refluence effect of venetian blind (or whirl hole) and manger board causes intake resistance large, enter the impurity after gas handling system not easily to discharge, affect the working life of filter core, increase later stage manual maintenance cost high and also can affect the travelling comfort of occupant.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of engine charge pre-flock system, in order to improve the turbidity test of engine charge.
The technical solution of the utility model:
A kind of engine charge pre-flock system, comprise pre-chimney filter, eddy flow fan, steam outlet pipe, support, it is characterized in that: described pre-chimney filter is a segment pipe, arranging at the axial position of pre-chimney filter inside has at least the eddy flow of 2 rotation blades to fan, the steam outlet pipe that caliber is less than pre-chimney filter is arranged in after the eddy flow fan of eddy flow fan leaf airflow direction, and pre-chimney filter and steam outlet pipe are connected by support and form air-flow interlayer.
The beneficial effects of the utility model:
The utility model just increases a kind of pre-flock device in gas handling system front end, relative to traditional engine charge pipeline structure, have the following advantages: most moisture and dust can be made directly to discharge along the interlayer of suction tude under the effect of eddy flow fan, dedusting, water removal effect are good, convenient later maintenance, and air power noise can not be produced because wind direction sharply changes formation airflow breakaway.
